How do you tell how old a Papillon Dog is? The size of a Papillon Dog is mainly determined by the growth of the teeth, the tooth peaks and tooth wear, the appearance and color, etc. Teeth begin to appear in about 20 days, and the primary incisors are all fully formed at 4 to 6 weeks old, and 2 to 6 weeks old. The baby teeth begin to be replaced at the age of 4 months. After the age of 8 months, all the permanent teeth are replaced. The permanent teeth grow in full length at the age of 1, and the peaks of the teeth begin to fade away at the age of 1.5 years.

In order to make it easier to master, the method of determining the age of a dog is introduced as follows:

Teeth begin to appear in about 20 days.

4 to 6 weeks old: The deciduous incisors are all in length. When nearly 2 months old, all the deciduous teeth are fully elongated, white, thin and pointed.

2 to 4 months old: Replace the first deciduous incisor.

5 to 6 months old: Replace the second and third deciduous incisors and deciduous canines.

After 8 months of age: All teeth are replaced with permanent teeth.

1 year old: The permanent teeth are all long, white and bright, and there are sharp protrusions on the incisors.

1.5 years old: The canine peak of the mandibular first incisor is worn to the level of the small peak. This phenomenon is called peak obliteration.

2.5 years old: The peak of the second mandibular incisor is lost.

3.5 years old: The peak of the maxillary first incisor is lost.

4.5 years old: The peak of the maxillary second incisor is lost.

5 years old: The peak of the third mandibular incisor is slightly worn, and the wear surface of the first and second mandibular incisors is rectangular.

6 years old: The peak of the third mandibular incisor is obliterated and the canine teeth are blunt and rounded.

7 years old: The mandibular first incisor is worn to the root of the tooth, and the wear surface is vertically oval

8 years old: The first incisor of the mandible is worn and tilted forward.

10 years old: The wear surfaces of the second mandibular and first maxillary incisors are longitudinally oval.

16 years old: The incisors are lost and the canines are incomplete.
